GREASE-CUP.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed August 6, 1914. Serial No. 855,401.

To all whom it may concern:

Be it known that I, LOUIS N. VINCENT, residing at Prescott, in thecounty of Yavapai and State of Arizona, a citizen of the United States,have invented certain new and useful Improvements in Grease-Cups; and Ido hereby declare the following to be a full, clear, and exactdescription of the in- 'vention, such as will enable others skilled inthe art to which it pertains to make and use the same.

My invention relates to improvements 1n grease cups particularly adaptedfor use on the moving parts of machinery, as for 111- stance on theconnecting rods of a locomotive.

The inventlon consists in the several features and combination offeatures as more fully hereinafter described and claimed.

It has for its object to provide agrease cup with means forautomatically feeding grease. said means being operated by the movementof the part of the machinery on V which the grease cup is mounted;

feeding of the grease.

It further has for its object to provide means for automatically feedingair under the follower of the grease cup.

It further has for its object to provide means whereby the height of thegrease in the cup can be ascertained Without necessitating the openingof the cup.

It further has for its object to provide a grease cup which is simple,inexpensive and durable in construction and Very effective andconvenient when in use.

Referring to the drawings:Figure 1 is a central vertical sectional viewof my invention. Fig. 2 a. top plan view. Fig. 3 a

bottom plan view of the cover of the grease cup. Fig. 1 a top plan viewof the spring pressed sleeve. Fig. 5 a side view in elevation of thefollower and its stem. Fig. 6 a side view of the air valve. Fig. 7 a topplan view of the air valve.

In the drawings in which similar reference characters denote similarparts throughout the several views, 1 represents the grease cup, shownas cylindrical in form but which may be made in any desired shape orform, which comprises a body portion or grease receptacle 2 with abottom 3 provided with a screwthreaded projection 4 having an outlet orfeed hole 5 through which the grease is fed to the part to belubricated. The; upper end of the grease receptacle 2 is provided withexterior screwthreads 6 and is closed by a cover 7, which is screwedonto the screwthreads 6, provided with a hexagonal boss 8, havingv ahole 9 extending through said boss and cover, and an interior circularshoulder 10. A. follower 12 is provided inside the grease cup receptacle2, which may have any well known packing rings not shown, appliedthereto to maintain a tight joint in'conn'ection with the saidreceptacle, said follower comprising a head 13, a circular projection 11and a stem 15 extending upward from said projection.

The projection 14: of the follower 12 is provided with a circularvertical recess 16 which extends upward to a point 17 and 18 are squareholes which extend laterally through the projection 14 and communicatewith the recess 16. An air valve 19 is provided comprising, a head 20adapted to contact with the bottom of the head 13 of the follower andcontrol the admission of air under said head of the follower, a stem 21which fits loosely in the recess 16 and a square pin 22 which fits or ismounted in a square hole 23 in the stem 21 of the air valve and servesto retain the air valve loosely in its operative position. A weight 21is provided having a hole 25 therethrough by which it is adapted to bemounted on the projection above the stem 15 of the follower and isdesigned to be reciprocated thereon between the top of the head of thefollower anda sleeve 26 by the vibration of the m0v fprov ments.

to all such vari t ons and mod fications'as ing part of the-machinery onwhich the grease cup is mounted. It will be seen that as the followermoves downward, under the pressure of the weight or rather thehammeringthereof, the extent of movement of the weight on the stembetween the follower and the sleeve 26 will always remain the same. Thesleeve 26, before referred to, has a socket 27 and an aperture 2.8 andis mounted on the stem 15 of the follower and seats on a shoulder 29formed by the top of the projection 14 and 'a spiral spring 30 encirclesthe stem 15 and one end is mounted in the socket 27 while the other endis mounted in a recess 31 in the cover 7. The spiral spring 30 is forthe purpose of constantlv or at all times maintainin a spring pressureon the sleeve 26 and the follower 12 and thereby sup lementing thepressure caused by the weight of the follower on the grease. The s ringpressed sleeve 26 also ser es as a vielding abutment for the weight 24during its operation on the stem of the follower.

Ihe several arts of the grease cup mav be made of anv' de ired size orshape to suit the reouirements of use.

' If it is desired to feed the grease when the'cup is at rest it is onlvnecessar to fill the grease receptacle of the cup full. place the folower on the s rface of the grease and then hv screwing the top downwardthe sho lder 10 w ll contact with the follower and grease will be forcedout of the outlet hole P3 bv the pressure of the sa d follower. The feedofthe grease is regulated bv changing the weight of the reciDrocntorvweight.

In operation the grease. follower and -otherparts are placed in the muser'ecep taclei the cover screwed tightly on and as the g ease cup isvibrated or reciprocated bv the motion of the moving part of themachinerv on which it is mounted the wei ht is caused to reci rocate beteen the fol ower and the spring pressed s eeve and t knock or hammeragainst the fo er wh ch causes the grease to be expelled or fed from thegrease receptacle throu h the feed hole 5 to the part to be lubricated.

I do not wish to he unde stood as limiting mvself to the specificdetails of con truction a d arrangem nt as h in described and illustrateas it is manifest that variations and m difications mav he made in thefeatures of construction and arrangement in the adaptation of the deviceto various conditions .of use without departing from the spiritand sco eof mv invention and im- I therefore reser e the right properl fallwithin the sco e ofrnv inven- .,tion andthe terms of thefollowing'claims.
